: Application filed October 20,1919. Serial No. 331,943.

1T0 all who knit may; concern:

Be it known} that I; HOMER G-QSTALEY,

a citizen of the United States, and a resident of Oakland, in the county of Alamedaand State of California, have invented certain new z'and useful Improvements in Nashing Apparatus ofwhich the following is a specifi i n My invention relates to machines for jwashing articles especially vegetables and lowing descriptionof the preferred form of my invention which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood that]: donot limit myself to the showing made by the said drawings and descriptlon,

' i asI may adopt variations of the preferred p form within the scope of my invention as set forth in the claims. .Referring to the drawings:

Figure 1' is a side elevation of one formof my washing apparatus.

Figure 2 1s a plan new of the structure shown in Figure 1.

Figure?) is a vertical sectional View of another embodiment of'my 1I1Ve1'1t1OIl,tl1G

plane of section being indicated by the line 3--3 of Figure 4, which isa plan view of the apparatus shown in Figure 3.

Vegetables such as spinach are particularlv hard to-cleanse from adhering particles of dirt and sand which lodge in the foldsandcreases of the leaves insuch a manner that an ordinary current of water -will not dislodge them. I have therefore devised means for giving the vegetables or I otherarticles or material aback-and-forth, reciprocatinglor shaking mot1on inastream of water, ,approximating' the movement im- As shown in Figures 1 and 2, my washing apparatu's comprises a tank 2 through which waterflogws entering through pipe 3 andv discharging through pipe a.- Two drums 6 and 7 are 'rotatably mounted in bearings arranged on the edges of the tank and are provided with pins 8 having blunt ends curved backwardly in respect of the direction of rotation. Preferably arranged below the drums in the bottom of the tank is a feed draper 9,'the upper reach ofwhich passes closely adjacent the ends of the pins 8. The draper is driven at a slow speed by the belt 10 from a conveniently disposed power shaft. A second draper 11" preferably with slats 12 thereon is arranged at the discharge end of the tank to carry out the washed material.

Means are provided for imparting to the drums (Sand 7 an interrupted but progres sive rotary movement in the direction shown by the arrows, the forward movements being alternated with reverse movements througha smaller arc. The resultant motion in respect of the pins 8 is a backandforth or reciprocating or shaking'one, which thoroughly washes the material lodged upon the pins. This motion is supplemented by an interrupted forward rotary movement of the drums which carries the material on ward through the machine.

Mounted for reciprocating motion upon the grooved rollers 13 arranged on the side of the tank is a slide or plate 14, connected by pitman 16 with the crank disk 17 rotated from a suitably disposed power shaft by the belt 18. Sprocket wheels'lS) and 20 are mounted at the ends of the reciprocating plate and are connected by a chain 21. the

.upper reach of which also engages sprockets the chain from the sprockets 22, a plate 23 is secured below each sprocket, the chain pa sing between the two. On the .1 nneshait with sprocket is a pulley 2%. which is driven by belt 26 from a power shaft lo cated vertically above the middle position of the pulley during the reciprocation ot the slide ll. The rotation ot the pulley .24; is relatively much slower than that the pulley l7. i-Vith the slide stationary, "the chain'Ql would 01 course rotate the drums continuously forward in the direction indicatcd by the arrows, but vith the reciprocation of the slide, the characteristic reciproeatory rotary motion of the drums is 'produced, the speed oi the forward move ment being determined by the sum of the speeds of the slide and the chain, and the speed of the reverse movement by their dilference.' Since lJOillr movements of each phase occur during an equal period oi. time,

f it follows that. durinpf the. forward move ment the drums rotate through a greater are than during the reverse movemenuand. the diil'erence in the length of these arcs is the net forward of each phase. resultinp: in a slow rotation of he drums in ad dition to th reciprocating movement.

V The vegetable or material to be washed is thrown into the tank at the end shown at the right in the figures ofthe drawing.

l loating. pieces are cai it directly by the pins. 8, while the matcral that sinks is carried by the feed draper 9 toward the first drum 7 and the pins thereon. Caught 1 hy'the pins, the material is repeatedly shaken fw ater.

or moved back and forth in the water and at the same time given a progressive movement toward the second drum, where the process is repeated. It is not-intended that the material shall. he carried around on the drums. The curved ends of the pins 'lacilitate the disengagement of the material which drops back into the water as the p ns rise toimrd a horizontal position above the 3y the'time the material has passed 7 the second drum it has been. shaken clear of all adheringparticles and thoroughly washed. 'iks the washed. material reaches the dischargeend of thetank, it"lodg 'es on the slatted draper 11 and is'earried out of e machine and permitted to iiall into an appropriate receptacle.

In Figures 8 and 1- 1 have shown an embodiment of my invention which ditl'crs from that ust explained by the inclusion of a steel doormat belt 31 arranged upon the drums. In this case the pins 8 are secured by rivets to the links of the belt and are ar rang'edan parallel rows upon the belt as. shown in Figure l.

The operation of the apparatus is the same that first described but with the added advantage that the vegetablesor other material being washed. are kept sulunerged con tinuously during their progress through the tank, the lower reach of the belt preventing the material from rising to the suri'ace hetween the drums. This-construction possesses a further advantage in that the distance between the drumsmay he madesuch as to give alonger washing period than is possible with the Figure 1 construction.

From the above, it will be clear that the pins not onlyshake the material inthe tank back and forth in the-washing liquid, but together with the surface of the clrums or belt, impart to it a steady forward move ment toward the discharge end of thejtank. For this reason I'do not consider the 'inclusion oithe feed draper9 essential tothe operation of the apparatus and I may omit this element from the. structure.
